SPECIFICATION fetming part er Lettere Patent No. 791,659, dated June e, 1905. Application filed March 31, 1905. Serial No. 253,038.

To all whom t may concern:

Be it known that I, SIGMUND SzEN'rJNossY, a citizen of Austria-Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bridges, of which the following is a specication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to bridges for use in connection with gates on elevated railways, tunnel, or subway railways for closing the space between the doors or gates of a car r cars and the platform at the side of a train or at the side of a railway-track; and the object of the invention is to provide a gate of this class which is operated by a sliding door or gate at the end orends of the cars, a further object being to provide a device of this class which may beused in connection with gates on public highways and other roads in which the opening of a gate would project a bridge across a narrow chasm, stream, or the like; and with these and other objects in view the invention consists in a device or apparatus of the class specified constructed as hereinafter ldescribed and claimed.

The invention is fully disclosed in the following speciiication, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure l is a side view of a gate and crosssectional view of a bridge involving my invention; Fig. Q, a section on the line 2 2 of Fig. l, and Fig. 3 a section on the line 3 3 t of Fig. 2.

: one corner of the gate a at the lower righthand corner, as shown in the drawings, is a vertical shaft c, provided with an upper pinion or gear c2, which operates in connection with the rack-bar t2 on the gate a and with a lower pinion or gear c3, which operates in connection with thevrack-bar b2 on the bridge b. With this construction it will be apparent that when the gate is moved in the direction of the arrow m the bridge Z2 will be projected in the direction of the arrow y of Fig. 2, the line of the movement of the gate being at right angles to the line of the movement of the bridge at all times.

It is a well-known fact that in elevated-railway constructions and also in underground or subwayT railway constructions there is frequently considerable space between the cars and the platforms from which the cars are entered, and this frequently results in serious and sometimes fatal accidents by reason of persons on leaving or entering the cars stepping into the spaces between the cars and the platform; but with my improvement these spaces may always be closed by the gates themselves in opening said gates, and in closing said gates the bridge or bridges lwill be drawn back beneath the platform of the cars. It will also be evident that the extent of the movement of the bridge may be regulated by the gearing by which the bridge is operated, and this movement of the bridge may also be regulated in various ways.

My improvement-also is not limited to any particular construction of' ,the bridge or bridges, and collapsible or other bridges may be employed.

It will be apparent also that my improved bridge construction may be used on ordinary roads,.highways, tramways, or other railways, all that is necessary in this connection being to make the bridge of suitable dimensions and strength and to regulate the gearing by which it is operated and in accordance with the requirem'ents of the particular case.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a sliding gate and a sliding bridge movable at an angle to the line of the movement of the gate, said gate and bridge being geared in connection wherebyT the movement of the gate will also move the bridge, substantially as shown and described.

2. A sliding gate mounted in suitable sup ports, and a sliding bridge mounted thereunder and movable at an angle to the line of the movement of the gate, said gate and said bridge being geared in connection, substantially as shown and described.

3. A sliding gate provided with a rack-bar, a sliding bridge mounted beneath the gate and also provided with a rack-bar, the line of the movement of the gate being at an angle to the ence of the subscribing Witnesses,this 30th d ay of March, 1905.
